B-Line Eaton series runway cable support bar, 5.21875" height, 5.21875" length, 6" width, Steel tubing, 13 gauge, Cable support bar, Yellow zinc

The SB16106YZ cable support bar measures 6 inches across its width, with a 5.21875 inch height and 5.21875 inch length, so it is sized for a 6 inch wide runway section. Measure the inside width of your runway stringers before ordering, because a bar cut for 6 inches will not span a wider tray.

The SB16106YZ runway cable support bar is UL Classified. That is the rating carried on the part, and it is what an inspector or a spec reviewer will be looking for on cable support hardware in an electrical or telecom room.

Yellow zinc plating on the SB16106YZ is a bright, indoor-duty finish over the steel tubing. It suits conditioned interior spaces like data rooms, equipment closets and MDF/IDF rooms. For exterior runs, wash-down areas or corrosive environments, specify a hot dip galvanized or stainless support instead.

A support bar like the SB16106YZ spans the runway to hold cable up off the bottom and keep bundles from sagging between stringers. A J-hook, by contrast, is a standalone catenary hook fastened to structure for free-air cable runs with no tray at all. If you already have ladder runway in place and just need intermediate cable bearing points, the support bar is the right piece; if you have no runway, you are looking at hooks or bridle rings.

Order it as B-Line SB16106YZ. The SB161 prefix is the runway cable support bar series, the 06 reflects the 6 inch width, and YZ is the yellow zinc finish.

The bar is 13 gauge steel tubing rather than formed strap, so it resists twisting under bundle weight better than a light stamped part of the same footprint. Tube also gives a rounded bearing surface, which is what you want where jacketed cable rests on it. For very heavy feeder or large copper bundles, size the number of intermediate bars to your cable fill rather than relying on a single bar mid-span.
